Tomenosuke are releasing a new Lazer sight rod option.
Release about March 2018.
Simple interchange swap out with the existing Blaster's Sight Rod.
No wiring needed >>> special design "push-button type" Green LED to switch on / off. Special LED run time 30 hours continuous.
The LEDs are easily removable and are replaceable.

post codes in japan are in this format: 100-0001
in my case I put BE 1190 to fill both cases. doesn't matter U guess.
I personally changed my mind and didn't pay the invoice. It was 90€, which was way too expensive for me considering what it was.
I'll just wire my green leds myself...

Hey,
just for your information, comprarobe on ebay is now selling a lit laser side rod for 69dollars (+ shipping cost), might be a good alternative for people in Europe:
